SRAM RED® DZero Power Meter

REACH A HIGHER LEVEL

Quarq’s next-generation power meter platform, DZero, is named for the DZero Experiment, one of science’s most accurate and innovative projects to detect subatomic particles moving at the speed of light.

With a new measurement circuit, a revised strain gauge design, improved accuracy throughout the pedal stroke and software advances built into the Qalvin App, DZero represents the state of the art in power meter technology.

This power meter works for every discipline: Road, triathlon, time trial, and cyclo-cross. The chainrings are replaceable should your bike, discipline, or ability change.

A direct force power meter that measures total power output from both legs with +/-1.5% accuracy

Dual Bluetooth low energy and ANT+ let you choose how to capture the data

11-Speed Product Compatibility Information
SRAM 11 speed components were designed to be paired with matching SRAM 11 speed components to ensure proper function. We can only guarantee the performance when used with the correct SRAM branded components.

The chainrings are designed for an optimized shifting performance with the Yaw front derailleur. The stiffer rings (5mm 7075-T6 aluminum CNC-machined) feature upshift rivets with an advanced design adopted from SRAM XX. CNC machining allows for precision control of each tooth shape, ramp, and nearly every shifting feature of the chainring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimized performance.

Servicing SRAM components often requires advanced bicycle knowledge and specialized tools. We work closely with your local bike shop to make sure they can answer your questions and service your SRAM components. Please contact your dealer before servicing any SRAM product.

“In a world dominated by Shimano, it’s good to be able to ride SRAM Red again. It’s easy to forget just how slick SRAM’s top-end groupset actually is. The Double Tap shifting snaps into gear superbly every time, and the speed with which you can ship across the block and the smoothness of the trim-free Yaw front derailleur are both marvels. Oh, and it’s also the lightest groupset out there. Impressive.”

"After spending three months riding it, it’s safe to say that eTap is a truly revolutionary component group that raises the bar for what an electronic drivetrain can be. And it may even redefine the way we shift our bikes."

Bike Company Switches Gears in Road Shifting, Going Wireless | The New York Times

"But SRAM’s new offering, Red eTap, effectively turns bikes into micronetworks that allow shifting that is both wireless and electronic."

"Despite wireless advances since then, SRAM quickly discovered that off-the-shelf wireless systems were not up to the job. With Bluetooth, for example, there was too great a time lag. Other systems strained batteries. As a result, SRAM was left to come up with a wireless system of its own."
